I thought I'd bring it up because of some of the comments to both my Rush Limbaugh posts and some of my other recent posts.
Yes, if you severely restrict your caloric intake you will lose weight. But just losing weight in the short term is meaningless. What matters is losing weight for good and not gaining it back. It matters not just for your self-image but for your health.
I quoted a doctor in this post who I think describes the real reality of weight loss well: http://losingweightafter45isabitch.blogspot.com/2010/11/proving-that-rush-limbaugh-really-is.html
As a refresher, here is just part of what the Doctor said:
The two-month timeline here is important for another reason. Over the long term, controlling calories means either going hungry, or finding a way to feel full and satisfied on fewer calories. Here's where the quality of calories certainly does matter. Foods of high nutritional quality include, among their many virtues, the capacity to produce fullness on fewer calories. Eating until full and yet being lean is having your cake and eating it too -- but snack cakes will never get you there!
That's the nut. You can lose weight on Twinkies, but you won't lose the weight for good. Restricting calories on Twinkies is not sustainable. You'll feel hungry, and won't have the energy you need to complete your day. It's merely the crazy, crash diet of the Yo-Yo cycle.
If you want to lose weight and keep it off you have to make permanent, life-time changes to the way you eat. Eating unprocessed foods, and focusing on eating fresh fruits and vegetables will leave you filling full, satisfied and able to complete your day.
And, that ain't no Yo-Yo.
